@gsoares, is the weibo watermark not a third-party watermark?

No, because weibo is not a third party here
Weibo is not the artist (first party), nor did it commission, contract or employ the artist (second party). So what is it? Am I misunderstanding the concept? That artists willingly upload there doesn't change the fact the website is what is modifying the image, not the artist.
In theory, it could be that Weibo mandates that all who upload there must insert a Weibo watermark themselves beforehand, but that seems technically difficult or impossible to enforce, and highly unlikely.
